MOUNTING CONSTRUCTION FOR METERS Filed June 24, 1927 INVENTOR v Walter G. Mylz'us.

' ATTORNEY Patented May 19, 1931 NUNITED STATES PATENT OFFICE WALTER G. MYLIUS, OF WILKINSBURG, PENN SYLVAN IA, ASSIGNOB TO WESTINGHOUSE ELECTRIC & MANUFACTURING COMPANY, A CORPORATION OF PENNSYLVANIA moun'rme CONSTRUCTION FOR METERS Application filed June 24,

My'invention relates to electricalmeasuring instruments and comprises, more particularly, a construction involving the mounting of an elongated member for supporting a plurality of intermeshing gear, wheels in such manner that the member shall besubstantially free from buckling or torsional strains incident to the securing means.

My invention resides in apparatus for mounting a register on a meter-supporting frame in such manner that the tendency of the register mounting plate to buckle .issubstantially obviated while preventing improper meshing of the gear wheels in the gear trains; it is further characteristic of my apparatus for this purpose that it is extremely simple and embodies the desirable function of permitting removal of the register from the front of the measuring instrument. I

It is further characteristic of my invention that there are no loose screws or washers associated with the assembled apparatus, my novel mounting permitting substantially all pressure forces existing between the securing means and the frame to be released in a simple manner.

It is further characteristic of my invention that the register may be placed in position to be secured to the frame in a manner requiring substantially negligible support while the operation of clamping or securing the register to the frame is being performed;

It is further characteristic of my invention that an elongated register having a flexible mounting constructed in'accordance therewith, may be mounted on separate movable frames. Such arrangement permits a facile assembly of the register to the frame and a delicate and accurate intermeshing of the pinions on the main driving shafts, and the gear wheels on the register, by virtue of the fact that my flexible mounting permits of an adjustment of the frame structures whereby gear wheels of the registers may be properly meshed with the driving pinions.

My invention resides inapparatus of the character hereinafter described and claimed,

1927. Serial No. 201,175.

the foregoing and further characteristics of my invention being determinable from the following description.

For. an understanding of one of the forms my apparatus may take, reference is to be pansible member constructed in accordancewith, and for the purpose of, my invention.

Fig. 3 is a plan view of the device shown in Fig. '2, illustrating how. the expansible member engages one of the frames.

Fig. 4 is a view, in cross section, of the expansible member shown in Fig. 2 taken on the line IVIV, and

Fig. 5is a plan view of the deviceshown in Fig. 2, illustrating how the expansible member engages the other frame.

Referring to Fig. 1, 1 and 2 are electrical measuring instruments mounted on a panelboard 2. The instruments co-operate with each other through a ball mechanism 3 to indicate, respectively, volt-ampere hours on a register 4 and kilowatt hours on a register 5. The. registers 4 and 5, with their associated; gear trains, are suitably mounted on an elongated member 6 that supports a portion of the ball mechanism 3 and holds the gear wheels intermeshing with the operating gears of the instruments 1 and '2 improper cooperative spaced relationship. I

The plate 6 must be in exact alinement and should be free from all-stresses or torsional. effects incident to its own mounting in order that the delicate and co-operating gear wheels shall be free from extraneous forces and other undesirable characteristics arising by virtue of a twisted or bent plate.

In accordance with my invention, I secure the meter plate 6 to projecting members or studs 7 and 8 that extend from the bases or frames, respectively, of the meters in such manner that the plate 6 is held in substantially fixedspaced relationship to the frame of the meters and issubstantially free from any twisting or torsional efi'ects, i; e., the strains exerted between the supporting structure and the studs 7 and 8 to hold the mount ing means in position are entirely eliminated with respect to the member 6. i

In accordance with my invention, lemploy a plurality of expansible members that co-operate with the plate 6 and the Studs 7 and 8 in suchmahner that the plate6 is secured in relatively fixed spaced relationship in any" desired position.

An expanslble member constructed for purposes of my inventlon as shown in Fig.

2, for example, consists of: a membe'rf9 of: substantially drum shape having a circumferential projection 10 co-operating with an; ,insert -l1indasuitable opening in the plate 6. The member 9 may 'befexpandedflby any 7 convenient means, for example by providsecured to the respective supporting'studs ing: a tapered threaded n inner portion a 12' I adaptedtoceroperate with ascrewl3-,.which,

when rotated, effects separation or spreadingof portions l tand 1 5 ofthe expans'ible member 9.. Portions 14 and; 15 are separatedby a slotlG and co-operatively engage the surface 17 between: the expanslble -member 9Land the stud7 I Theexpansible member 9-1and the open ing in thestud 7 for the reception of said member 9 may be of 1 any convenient shape, but I prefer that they shallmbe substantially circular and fit? relatively close, sot that,

lVhile the. ends of the plate 6 maybe :andthensecuring the other end of the plate bymeans of aplurality of expansible members adapted to co-operate with an opening the stud Sthat will permit relative longitudinal motion between the .studa8 and the plate 6". Fig,:'1,illustrates how the ex.- pansible; members '9 co operate with the stud Ste-permit longitudinal changes in the position of the stud 8 in order thatgearQQ of the meter-2i may be properly meshed with the gearwheel 2i of the plate 6'. Thevstud 8-isprovided with: slots 18 that longitudinalr ly extend in a direction similar to the direction of the longitudinal axis of the plate 6.

Theexpansible members 9, when expanded hyturni-ng the screws 13, engage the" lateral facesof theslots 1 8 and secure the plate I 6 in a position free from transverse or lat eral twisting.

with slots 23 and 24 so that the longitudinal position of the frame'22 may be var1ed until the gear .wheelu2l; and the pinion; wheel 20 WlIlClLPIOSitiOH itisretained by the friction-5 al' engagement of the expansible members withtheirxcorresponding openings in the studs, then tighten the single expan'sible member on the leftzend of therplate 6' and.

The frame 22 of the meter 2 is provided then tighten; the plurality of;- vexpansiblfi members on: the othere'nd 'ot theplate (latter the proper gears have been meshed. .When

the plated is secured to the studs 7 and 8 vin thisimanner, theintermeshing gear wheels of the registers tand- Sand-the intermeshing gearifwheels between the driving mechanisms of the instrumentsv land 2 andthe driven mechanisms mounted; on the plate; 6 are held in perfect a-linement, free from torsional: forcesand other undesirable mesh ingrcharacteristi'csw I f I a 7 While Irhave shown: a preferred embodiment of means for: securing a register plate to a supporting frame, it will of coursebe obvious that the sameresult, as hereinbefore disclosed, .may' be accomplished by slightly altering the construction of the mechanical parts mentioned above; for; example, the expansible member 9; may be substantially square 5- or of rectangular, cross section instead ofbeing circular, but I desire that all .snchclianges or modificationsshall be .incl-uded 5 within the spiritofgthe appended Ircl-aim asmy invention: I 1
